ICANN has released a "living" graphic aimed to provide a high-level view of how the internet is run attuned for those less familiar with the inner workings of the internet infrastructure ecosystem. Quoting from the document:

No One Person, Company, Organization or Government Runs the Internet
The Internet itself is globally distributed computer network comprised of many voluntary interconnected autonomous networks. Similarly, its governance is conducted by a decentralized and international multi-stakeholder network of interconnected autonomous groups drawing from civil society, the private sector, governments, the academic and research communities, and national and international organizations. They work cooperatively from their respective roles to create shared policies and standards that maintain the Internet's global interpretability for the public good.
